Why does doping continue to cast a persistent shadow over sport? Is it really a contemporary phenomenon, or has it accompanied athletes and competitions since their inception? And to what extent do current anti-doping policies protect fair play... or excessively punish the athletes themselves? From the marathon runners who ran on strychnine in the early 20th century to the death of Tom Simpson on Mont Ventoux, from secret doping programs during the Cold War to Russia's expulsion from the 2018 Winter Games, this book traces an uncomfortable and fascinating history: that of the eternal struggle between drugs, sport, and power. With historical rigor and an agile style, Doping: Between Glory and Cheating shows how the fight against doping has been marked by contradictions, political interests, and disproportionate punishments that have sometimes turned the athletes themselves into victims. A book that, while narrating the historical evolution of doping and anti-doping policies, invites us to question the dogmas of clean sport and proposes a new approach: one that puts those who deserve it most, the athletes, at the center.
